JAR-CLOSU RE.

SPECIFICATION forming part of Letters Patent No. 366,663, dated July 19, 1887;

Application filed April 15, 1857. Serial No. Bil-Hill.

' plication to that class ot'jars wherein the contents are prevented from coming in contact with the metal of the cap.

It consists in the novel construction and arrangement of the parts whereby the cap may be fitted to the jar with convenience and without less of time, the contents of the jar are kept from contact withthe metal of the cap, and whereby the construction of the parts is simplified.

In the drawings, Figure 1 is aside elevation of a jar provided with this invention. Fig. 2 is a vertical section of the same. Fig. 3 is a plan view of the same. Fig. 4 is a plan view of an alternative form.

The letter A designates a jar constructed of glass or of any other suitable material, and

provided at the neck B with the semicircular cam shaped flanges G. The said flanges are separated by the spaces D upon opposite sides of the said neck, and are correspondingly inclined upon their under surface. The neck B extends above the said flange for a short distance, substantially as shown, to form an angle at its junction with the flanges C. By means of soft packing placed in the said angle leaka e is effectually prevented. This construction obviates the necessity of ii nishing carefully the mouth of thejar to make a closcjoint.

Fitting loosely over the neck B is a cap, E.

-The said ca is )rovided with a flan e F extending around the lower edge. The said flange extends over the tops of the flanges C, and is shaped to form a close joint with the same. When the said flange F rests upon the flanges C,a small space is left between the top of the cap and the mouth of the jar for the accommodation of aglass disk, G, which is fitted over the said mouth to prevent the contents of the jar coming in contact with the metal of the cap.

(No model.)

In order to secure a close joint between-the said disk G and themouth of the jar, a rubber cushion, K, is placed in the top of the cap, which, when compressed, presses the disk G- down upon the said mouth. Passing over the said cap E is a small yoke, II. The said yoke consists of a continuous wire bent to an oblong shape and the ends joined, substantially as shown. It is then placed upon the top of the said cap and soldered thereto, extending an equal distance to either side of the center of the said cap. 30th sides are then bent at an angle of ninety degrees at apoint directly over the edge of the flange F, which theytouchaud are soldered to, to make them rigid. The short rounded ends which are left below the said flange F are now bent inwardly at an angle of ninety degrees at a distance from the said flange equal to the thickness of the middle of the flanges O. Theinwardly-projecting portions I of these ends are adapted to pass through the spaces D and extend under the flanges O, substantially as shown. \Vhcn the parts of the cap are'put thus together and the jar is tilled, the cap is placed thereon, so that the projections I pass through the spaces D.

In this position the flange F is raised slightly off the flanges G by reason of the glass disk G resting upon the mouth of the jar. By turn ing the cap now in the direction of the enlarged ends of the flanges O, the projections I will run down the inclined face of the same and draw the cap down until the flange F rests upon the flanges 0, when themotion is stopped by the jamming ot' the said flanges between the said flange F and the projections I. In this position the cap is locked upon the jar. It can be unlocked by moving itaroundin the opposite direction from that last described un til it reaches the spaces D, when itis lifted off.

By placing an ordinary rubber band upon the flanges O, I obtain a perfectly water-tight joint at that point, and thus prevent leakage independently of the fitting of the glass disk G and the mouth of the jar.

The form shown in Fig. 4 differs from the one above described, in that it has the lugs L extending from the flange F between the sides of the yoke II, whereby that construction is strengthened.

What I claim is 10 a glass disk fitting the said cap and resting on the mouth of the said jar, and a rubber packin g interposed between the top of the said cap and the said disk, all combined substantially as set forth.

In testimony whereof I aflix my signature in 15 presence of two witnesses ANDREW J. .HAVENS.
